VENDING'r-MACHINE.

Application filed March 21,

To all whom 'it may concern:

13e it known that we,LoU1s lI-l. Dueon'r and THoMi-is A. KiLLMAN, citizens of the United States, residing at Nashville, in the county of Davidson and State ol Tennessee, have invented certain new and useful Improvements in Vending-Hachines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to a new and novel vending machine and more particularly to a` machine ot' this character which is primarily adapted for the vending ot newspapers.

The object of our invention is to provide a vending machine ot comparatively simple construction which is adapted to be automatically actuated by a coin or coins to singly deliver newspapers therefrom.

Another object is to provide means for preventing the operation of the delivering mechanism without the insertion ot a coin or coins ot' the proper denomination.

A still further objectis to provide a. movable belt which is adapted to carry and deliver the papersj and improved means for but one papermay be discharged when the proper coin or coins are inserted.

JAnother object is to provide suitable means for preventing` the insertion of coins after the machine has become exhausted.

llVith these and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings7 in which-- Figure 1 is a perspective view oit' a miv chine constructed in accordance with our invention.- the housing of the operating meehanisin being removed and Vthe casing partly broken away; Fig. 2 is a perspective view illustrating the delivering and operating mechanism removed from the casing showing the arrangement of the parts after the coins have engaged and released the oseillatory loc-king bars; Fig. 3 is a vertical longitudinal section through the casing and parts of the mechanism; Fig. 4 is an enlarged section taken on the line W4C of Fig. 3; Fig. 5 is ay detail section taken on the line 5 5 of Fig. l; Fig. 6 is a side elevation of the coin receiving wheel; Fig. 7 is a similar view showing the position of the wheel after the coins have released the locking bar; and

Fig. 8 is an exterior perspective view of the machine.

Referring in detail to the accompanying drawings 5 indicates the easing in which the mechanism of our machine is arranged. This casing is preferably constructed in the form shown in the d 1awiugis and comprises a. lower substantially rectangular body portion and the upper cylindrical portion 7 which forms a housing for the paper carrying roller and is of suiiicient diameter to permit of said roller carrying a large 'number of newspapers. The manne-r of charging the machine and arranging the papers for successive delivery will be more fully hereinafter set forth.

ln carrying out the purpose of our invention we have devised a delivery mechanism of novel construction and one which is extremely simple whereby the danger of the same getting out of order is to a large extent eliminated. This mechanism comprises a plurality of rollers arranged in the relation shown. The drum 8 mounted in the sides ot the lower portion G of the casing may for convenience be denominated the power drum, while the roller 9 which is rotatably mounted in the ends of the cylindrical housing 7 of the casing constitutes the power roller upon which the papers are carried for delivery. The drum 8 and roller 9 each have one end of a movable belt 10 secured thereto. Between the power drum and the paper roller this belt traverses the idler rollers 11 and 12, respectively, which are rotatably mounted in the lower body portion of the casing and in parallel relation to the drum 8 and roller The paper carrying belt extends from the power drum 8 around the idler 121, then forwardly and around the roller ll from whence it passes around the roller 9 and to which it is secured as previously stated. It will be obvious that if papers are laid upon the moving belt 10, the belt together with the papers carried thereby will be wound upon the roller 9 and thus fed into the machine, the papers being ar ranged in spaced relation between the successive circular layers of the belt, the belt roll gradually increasing in diameter' until it approximately fills the interior of the housing 7. It is further apparent that in order to insure success in the operation Tof the machine the papers must also be delivered therefrom at equal intervals so that site end 'of the .shaft 13. It will be obvious that as this nut is threaded inwardly upon the shaft 13, the said shaft will be drawn through the hollow drum 8 and as the ratchet 22 and flange 25 are rigidly fixed thereto, they will likewise be drawn inwardly, the flange moving into the end of the drum and forcing the bowed plates toward each other, thereby increasing the friction between said plates, the head wall 2G and the flange 25 so that when the crank is manipulated, the coin receiving` wheel 14 and the drum will be simultaneously rotated to deliver the paper to the purchaser. The end of the drum 8 at the opposite side of the casing to the coin receiving mechanism is spaced from the casing wall by means of a. washer 29, thereby preventing wear upon the wall of the casing. This washer may from time to time be replaced by a new one. By the construction above described the coin wheel and crank may be turned l'iaclm'ardly without rotating the power drum S, but when moved in the propel? direction the spring pawl 23 will engage the teeth of the ratchet 22 and lock the drum to the wheel, thereby causing the same to turn and move the belt for the delivery of the paper.

In order to prevent the fraudulent operation of the machine we provide means for locking the idler roller 12 against rotation, whereby the friction between the belt and said roller will be such as to obviate the movement of the belt therearound-when the crank is turned and will cause the coin receiving wheel to move independently of the power drum 8. This locking means is adapted to be actuated by the coin or coins inserted for the purchase of a. paper and which is arranged substantially as follows: The stub shaft 30 on one end of the idler roller 12 projects through the casing wall and has rigidly secured thereon a disk 31. This disk is provided at dia-metrically opposite points in its periphery with the notches or recesses 32. These recesses are adapted to receive the end of an oscillatory locking bar 33. This bar is pivoted intermediate of its ends, as at 35, upon the casing wall and is normally held in engagement with the periphery of the disk by means of a leaf spring 34, one end of which is secured to a stud fixed in the easing. The forward end of this locking lever extends above the periphery of the coin receiving wheel 14- and isformed with a lateral arm or plate 36. This plate 36 is adapted to be engaged by the coins carried by t-he wheel 14 as the crank 18 is turned, whereby the forward end of the locking lever or bar 33 will be raised and the rear end thereof the recess 32 whereby the idler roller 12 may be rotated to permit of the movement of the delivery belt. The spring 34 will hold the end off the lever in engagement with the with a single operation of the machine but one paper will be delivered to the purchaser. The means whereby this result is attained will also be later set forth in det-ail. The operation of the delivery mechanism and the movement of the paper carrying belt is controlled by means 0f suitable coin actuated mechanism which is adapted to cooperate with the power drum 8 in such manner to prevent the rotation of said drum unless the proper coin or coins are inserted. This coin actuated mechanism is arranged substantially as follows: A shaft 13 extends longit-udinally through the power drum or roller 8, said drum being hollow. This shaft extends beyond the sides of the casing 5 and has loosely mounted on one end thereof a coin receiving wheel 14. This wheel formed with a peripheral groove providing a coin raceway 15. This raceway is positioned beneath and in alinelnent with the lower end of the coin chute 1G. The wheel 14 is also formed with a central extension 17, and a crank handle 18 is arranged thereon and is secured to said extension by means of a set screw 19. A plate 20 is arranged over the outer face of said handle and the eXtension 17 and is secured on the end of the shaft 12 by means of the screw 21 which has threaded engagement therein. Thus the crank handle and the coin receiving wheel are united for mov-ement upon the end of the drum carrying shaft. The power drum 8 is also loosely mounted on the shaft 13 and is adapted for independent rotation. It is obvious, however, that in order to move the belt- 10 to deliver the papers, it is necessaryto have unitary movement of the coin wheel and the drum when the crank 18 is rotated. This connection we secure in the following manner: Located upon the shaft 13 and on the inner face of the coin wheel 14 there is a ratchet wheel 22. The teeth of this ratchet are adapted to be engaged by a spring'held pawl 23 mounted on the face of the wheel 14. sleeve 24 is formed with the ratchet wheel 22 and extends inwardly within the end of the hollow drum 8. Upon its end an annular flange or plate 25 is formed. Disposed within the end of the drum 8 there is a head plate or wall 26. This head plate would preferably be formed integral with the drum as shown, and the plate 25 on the end ofthe sleeve24 is maintained in yielding spaced relation thereto by means of the oppositely bowed friction disks 27. These disks are loosely arranged on the shaft 18 and are united adjacent to said shaft. The periphery of one of said disks bears upon thc outer face of the head wall 26 and the other of said disks engages with the circular flange 25. The frictional engagement of these disks with the wall and flange is adapted to be increased or decreased by the adjustnnntof a nut .28 which is threaded upon the oppoperiphery of the disk 31 until the disk has made one-half of a revolution when said lever will engage with the notch in the opp0- site side of the disk and again lock t-he roller so as to prevent continued movement of the delivery belt. In this manner the delivery of .more than one paper with each operation of the machine is prevented.

The manner in which the coin or coins are carried by the wheel 14 and the means whereby said wheel may be arranged to receive one or a number of coins as the price of the paper varies, is shown in detail in Figs. G and T. It will be observed that the annularl groove or "aceway in the periphery of the wheel communicates with an inclined recess or socket 37 into which the coins are adapted to be directed. After the coins leave the lower end of the chute 16 and are deposited in the coin raceway of the wheeh they move downwardly between the base of the gig-oove in said. wheel and a guard plate or rail 3S. The lower end of this guard rail is formed with a projection or stop 39 which prevents the coins from being released and deposited in the bottom of the casing. The coins remain in this position as the wheel let is rotated and are adapted to be picked up and directed into the inclined socket 37 by means of a gravity dog 10. This dog is secured between the walls of the groove 15 by means of the pin 41 and its pivotal movement is adapted to be limited by the base of said groove and a pin 4t2 which is engaged by one end thereof. As this dog is brought into contact with the coins, the inner curved edge i-0 thereof will be disposed against the periphery of the coin and direct the same into the socket 3T. ln order to adapt the coiny wheel to receive different numbers of coins, we provide the saine with a plu 'ality of alined traiisverse openings 113 which extend therethrough upon opposite sides of the socket 37 and are adapted to receive a stop pin or screw at This pin let when in position limits ythe inward'movement of the coins into the socket and the opei'iings whichreeeive this pin are so spaced that the outermost coin will always projectbeyond the periphery of the wheel irrespective of the number of coins which are inserted to effect an operation of the mechanism. As the crank 18 is turned. the edge of the outer coin will be engaged with the underside of the plate 36 formed upon the forward end of the locking lever and `will elevate this lever against the tension ofthe springl 34 to release the idler roller 12 so that the delivery belt may thus be moved. The friction between the coin receiving wheel 14 and the power drum 8 having been adjusted for their unitary move-y ment, it will be obvious that after the locking lever has been released by the insertion ofthe proper come, the continued movement `lever from the disk 31.

of the crank will cause the belt 10 to traverse the different rollers and move a single paper carried thereby from the roll of belting upon the roller 9. This paper is adapted to be extended through aslot or opening l5 in the front of the casing 5. Then the locking lever is again engaged with the notch 32 of the disk 31, the added frictional resistance imparted by the roller to the movement of the belt will overcome the friction between the bowed plates-27 and the friction plate,

and head 26 of the drum 8 so Vthat the continued turning of the crank handle will only effect the independent rotation of the coin carrying wheel.

In order to obviate the liability of the gravity dog 4f() being disposed beneath and closing the lower end of the coin chute when the crank 1S is released, we attach the crank to the tubular stem or hub of the wheel 14e in such manner that if the saine is released upon the left hand side of the center of the power drinn., it will drop by gravity and move the gravity dog et() away from the lower open end of the coin chute into substantially the position indicated in G. lf, however. the handle is disposed to the right of the longitudinal center of the drinn 8 when released, it will be held in such position owing to the fractional connection between the'coin wheel and the power drum. To prevent the lijiackward movement of the handle 18, we mount upon the stud 35 on which the locking lever 33 is arranged, an arm 46. `This arm has pivotal movement and the free end thereof is adapted to engage with any one of a series of studs 47 formed upon the inner face of the coin wheel 1l. A. stop 11S is fixed in the casing wall and liniits the uliward movement of this arm and a leaf spring 49 is engaged therewith to insure its engagement with the studs carried by the coin wheel. ln this manner all danger of the gravity dog t0 being left in a position below the coin chute, whereby the proper operation of the mecl'ianisi'n would be rendered impossible, is avoided. At times it may be found desirable to lrelease the friction roll 12 so that the papers may be removed from the machine without the insertion of the coin or coins. For this purpose an arm or rod 5() is pivoted at one end to the locking lever"forward of its pivotal point and evtends upwardly and through an annular flange or rim formed upon a removable cap 51. The upper end of this arm is bent at an angle and is adapted to be grasped andlifted to overcome the tension of the spring 34 and disengage the locking The belt 10 which carries the papers will then be moved around the rollers and entirely wound upon the lower power drum 8, the papers, of course, being successively removed. The idler roller 12 is preferably formed. with a milled or knul-led surface to increase the friction of the same with the movable belt whereby the machine may further be rendered proof against fraudulent operation. The coin controlled operating mechanism is arranged in a housing or cover 52'." lThis cover may either be integrally formed with the coin chute and the cap 51 or eparately constructed. A cylindrical casing 52 is like wise provided between the cap 51 and the housing 52 to house the arm or rod 50.

After the locking lever has been lifted by the outermostcoin carried by the wheel 14 and said wheel has been moved to the posi.- tion shown in Fig. 7, the coins will gravitate outwardly and be discharged from the wheel upon a short curved plate 71 carried by the cover 52 and extending inwardly therefrom. This plate extends inwardly between. the cover and the side of the casing and acts as a guide for the coins so thatthey are deposited upon an inclined plate 72 which eX- iends inwardly and down vardly through an opening in the side wall of the main casing The curved plate 71 is closed at its forward end and secured to the annular wall of the cover 52 whereby the liability of the coins moving beyond the opening in the wall of the casing 5 is overcome.

Means are provided whereby the insertion of coins into the coin chute 16 when thev machine has become exhausted is prevented. This means comprise-s a spring yblade or arm 53, the upper end of which is formed with a laterally extending lug This lug is disposed across the coin o-pening in the upper end of the chute when the same is closed. lVe effect the automatic closing of the coin chute by providing a lever 55 formed upon its forward end with a wedge 56, said wedge having its inclined edge disposed against the resilient arm 53 and positioned between the same and the side of the casing The other end f the lever 55 is connected to one of the arms of a substantially U-shaped rock shaft 57. The arms of this shaft are disposed out of alinement, as shown in Fig. 2, and when in normal position the inner arm 57 is vertically disposed and the extreme end portion only of the wedge 56 is disposed between the casing and thc resilient arm 53, the lug 54 thereof heilig disposed inwardly and permitting` of the free passage and descent of the coins in the chute 16. The inner end 57 of the roel; shaft 57 is adapted to be engaged by a spring plate S. This plate is secured at one end to the periphery of the paper carrying roller 9 and extends outwardly at an angle thereto, the free end of said plate being disposed for engagement with the vertical. arm 57. Vhen the last of the papers have been delivered from the movable belt, this spring` plate 5S contacts with the arm 57 and forces the same forwardly, thus rocking the shaft 57 in its bearing and forcing the wedge 56 forwardly between the resilient arm 53 and the casing. By this movement the lug 54 on the upper end of the arm is positioned beneath Ithe coin slot and effectuall-y prevents t-he insertion of a coin therein. Upon the reverse movement of the paper carrying roll 9, the arm 57 of the rock shaft will be again engaged by the spring plate 58 and said shaft returned to its normal position.

The contact of the wedge 56 with the arm 53 will somewhat retard the forward movement of the lever 55 and place the plate 58 under compression so that it will be in position for the engagement of the arm 57 upon the reverse rotation of the paper carrying roller. The forward disposition of the outer arm of the rock shaft 57 and the added weight and downward inclination of the lever will cause the inner arm 57 to assume its normal posit-ion after the plate 5S has passed the same in the reverse movementof the roller, thus assuring the movement of the wedge to close the coin chute when the machine again becomes exhausted. The plate 5S will be closely held upon the periphery of the paper receiving roller as the carrying belt is wound and accumulates thereon. A short tubular leg 59 covers and protects the movable wedge carrying rod and may be secured between the cap 51 and the coin chute 16 in any preferred manner.

The paper carrying roller 9 has one of its studs 60 extending beyond the end wall of the housing 7 and has secured thereon a gear 61. This gear is adapted to mesh with a pinion 62 mounted upon a stud 63. A crank 64 is adapted to be detachably connected to the pinion 62 whereby the same may be rotated and through its engagement with the teeth of the gear 61 rotate the roller 9 to wind the belt 10 thereon. The removable cap 51 incloses the gear 61 and pinion 62 after the machine has been charged. The papers may be easily and properly placed upon the belt by opening the upper front cover 65 which is hinged, as shown at 66, Aand comprises an arcuate portion which forms a continuation of the housing 7 and a narrow inclined strip 67 which when the door or closure cover is open, serves as a support for the papers to be fed into the machine, the edges of the papers being disposed against the operators body. l The proper disposition of the papers upon the moving belt is secured by the engagement anddisengagement of the locking lever 33 in the peripheral recesses of the disk 31. As this lever is forced into the recesses by means of the leaf spring 34, the operator places a paper upon the moving belt, the crank 64 being turned by the operator or another to assist him in charging the machine. Thus it is evident that 'the papers will bc s uccessively discharged through the slot 45 1n the end to-receive the hinge rod upon which the a staple secured in the cylindrical body of door is mounted. This door carries a hasp 69 which is adapted to be inserted over the housing, said staple receiving a suitable padlock 70 by means of which the casing is securely closed and unauthorized tampering with the mechanism'of the machine prevented. It will be obvious that, if desired, the idler'roller 11 may also be formed with a milled surface to increase the .friction upon the belt, but this is not believed to be necessary, the frictional contact between the roller 12 and the belt being amply suflicient to overcome the friction induced by the engagement of the resilient plates with the friction plate 24. carried by the coin receiving wheel and the power drum.

From the foregoinoit is believed that the operation and construction of our improved vending machine will be readily understood. The mechanism is comparatively simple and the various parts are so arranged as to insure the positive delivery of a single paper upon the insertion of the proper coin or coins. The operating mechanism is also adapted to be actuated by the insertion of a nickel at which price Sunday newspapers are generally sold. The inclined socket 3,7 in the coin wheel being only of suliicient width to receive a copper cent, it is obvious that as the nickel is `of greater diameter it will not enter entirely into said socket. then the nickel is inserted in the coin slot, it will strike in the outer open end of the socket 37 with considerable force and engage with the opposite walls of said socket at ap- .proximately its center, the gravity dog ll() assisting in holding the nickel in position until it has performed its function of lifting the oscillatoryl locking lever It will he apparent that if found desirable, a uum- -ber of coin wheels 11i may be used, said wheels each being adapted to receive coins of different denominations, so that the machine may be utilized for the vending of other articles of merchandise. During the charging of the machine, the pivoted arm @L6 engaging with one of the lugs 47 on the inner face of the coin wheel 14 will hold said wheel and consequently the crank 18 against rotation, the hollow drum 8 rotating independent upon the shaft 13 as the belt is drawn therefrom. The friction rollers 11 and 12 are, of course, revolved by this movement of the belt, and owing to the friction produced by the bowed friction plates 27 betweenl the stationary plate 25l and the rotating drum 8, the belt 10 is kept taut at all times thereby causing the same to be wrapped closely around the paper carrying` roller 9 so that the belt is rendered capable of carrying a great number of papers in a comparatively contracted space.

By means of the construction above set forth, the vmachine may be easily charged with the papers and the means for connecting the coin controlled operating means and the power drum 8 is such that the operation of the machine without the insertion of the proper coin or coins is rendered impossible. Then the attempt is made to operate the machine without inserting the proper coins, the gravity dog l() will simply fall down until its lower end is disposed in the saine plane as the periphery of the wheel whereby the dog will move beneath the forward end of the locking lever 33 without lifting the same, whereby the friction produced between the roller 12 and the belt 10 will prevent said belt from slipping while the locking lever prevents rotation of the roller.

It will be understood that we do not wish to be restricted to the exact details of construction as above set forth, but reserve the right to make such changes in the arrange-V ment of the various elements and the form and proportions thereof as may later be deemed more desirable for the particular purpose to which the machine is to be applied.
